Often, entrepreneurs get so caught up in the excitement of early market traction and satisfying customer demands that they lose sight of how important a profitable and replicable business truly is. The Boomtown Accelerator program in Boulder, Colorado, aims to help small business owners prevent this early-stage mistake. Since Boomtown's founding in 2014, this 12-week program has helped over 80 companies develop and test their business models. It also assists entrepreneurs in understanding their company's numbers, as well as the key assumptions that directly impact their costs of sales and production. One of Boomtown's key success factors is the ability to create "a program that is best suited for the startup" and to focus specifically on "supporting and educating entrepreneurs where they need it most." This flexibility allows Boomtown to help founders get the most out of the intensive program, while providing them with practical tools and skills. While it can be great to close an early round of funding, the risks associated with early-stage investments are daunting, and an unsound business model isn't guaranteed to survive once funding runs out. While an outside investment can be a form of market validation, the real end goal is to build and grow a sustainable company that pays back investors and satisfies customer needs. Digging into the numbers and becoming financially literate aren't as fun as rapidly acquiring customers and seeing your idea turn into a viable company. But understanding the numbers and gaining the financial skills necessary for success are critical in managing a growing venture.
